STARLNK [Starlink Inu] Token

STARLINKINU.swapBack() (#406-454) sends eth to arbitrary user
Dangerous calls:
- address(marketingFeeReceiver).transfer(amountBNBMarketing) (#438)
- address(teamFeeReceiver).transfer(amountBNBteam) (#439)
- address(devFeeReceiver).transfer(amountBNBDev) (#440)
- address(rewardDistributor).transfer(amountBNBReward) (#441)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Contract ownership is not renounced (belongs to a wallet)

STARLINKINU._transferFrom(address,address,uint256) (#277-324) uses a dangerous strict equality:
- secondantibot && (firstbuy[recipient] == 0) (#286)
Don't use strict equality to determine if an account has enough Ether or tokens.
